The IP header size is .............
The IP header size is .............
The correct option is A 20 to 60 bytes long
The IP header size is 20
to 60 bytes long.
So the longest Internet
Header (IP header) size can be 15*32 Bits = 480 Bits = 60 Bytes. This is why
the header has a maximum size of 60 Bytes. The shortest header size is 20
bytes, where the IHL field has the value 5 (0101).
This 16-bit field defines
the entire packet size in bytes, including header and data. The minimum size is
20 bytes (header without data) and the maximum is 65,535 bytes. All hosts are
required to be able to reassemble datagrams of size up to 576 bytes, but most
modern hosts handle much larger packets.
The format of data that
can be recognized by IP is called an IP datagram. It consists of two
components, namely, the header and data, which need to be transmitted. The
fields in the datagram, except the data, have specific roles to perform in the
transmission of data.
The Total Length field is
the total length of the IPv4 datagram in bytes. Using this field and the IHL
field can indicate where the data portion of the datagram starts, and its
length. Because this is a 16-bit field, the maximum size of an IPv4 datagram
(including header) is 65,535 bytes.
